A comparison of resource use of insured and uninsured venezuelan migrants: evidence from the hospital setting.

BACKGROUND: There is no characterization of resource use in the hospital setting for immigrants in Colombia, we aimed to describe the resource use by Venezuelan immigrants, comparing those enrolled in the national health insurance system with those with and without the ability to pay. METHODS: Retrospective review in the billing data system of our Hospital from 2011 to 2020. We collected information for 6,837 hospital episodes associated with 1,022 Venezuelan patients, hospital's billing information for all services rendered was extracted. RESULTS: The mean cost per patient event were 4,595 USD for those without the ability to pay, costing 2.37 times more than a legal resident insured. Care in the ICU, inpatient days, surgery, and OB-GYN department consume most resources provided to vulnerable migrants. DISCUSSION: Enrolment in the national health insurance may allow better access to health services by vulnerable Venezuelan migrants and thus reduce resource use for the health system.
